Python异常处理try except理解

第1段代码未使用try except，遇到异常退出，print('abc')未执行。执行结果如下

def func1(a,b):
    return a/b

if __name__=='__main__':
     func1(1,0)
     print('abc')

D:\>python test_exception.py
Traceback (most recent call last):
  File "test_exception.py", line 12, in <module>
    func1(1,0)
  File "test_exception.py", line 2, in func1
    return a/b
ZeroDivisionError: integer division or modulo by zero

第2段代码使用try except，捕获到异常后继续执行print('abc')

def func1(a,b):
    return a/b

if __name__=='__main__':
    try:
     func1(1,0)
    except Exception as error:
     print error
     print('abc')    

D:\>python test_exception.py
integer division or modulo by zero
abc
